Basic Info.
Product Description
YBP-12/0.4 prefabricated substation (also called American-type prefabricated substation) mainly applied to 10kV urban and rural electric networks and to other public places, such as industrial and mining establishments, airports, railway stations, ports, expressways
The full-insulated and full-sealed structure requires no insulation distance and could guarantee personal safety;
Small size and compact conformation. YBP prefabricated substation is only 1/3 as big as European-type substation of the same capacity, and YBM only 1/2;
Flexible switchover between ring net and terminal supply;
Dual-fuse full-scope protection is enabled to reduce the running cost;
The box adopts corrosion-prevention design and special spray painting to face harsh environments;
Communication interface is reserved for distribution automation expansion.
Product structure High-tension cell
In the high tension cell, there are high-voltage input terminal, load switch operating handle, no- excitation pressure adjustment tap switch, push-in fuse, pressure release valve, oil thermometer, oil level gauge, pressure gauge, oil way and oil drain valve.
Low-tension cell
In the low-voltage distribution cabinet, there are wattmeter, voltmeter, ammeter, low-voltage master switch, low-voltage outgoing switch, reactive compensation unit, etc. Smart under-voltage controller can be installed as required to identify abnormal voltage of the low-voltage bus bar of substation. When high-voltage one-phase or two-phase fuse is burnt out and thus the voltage at the low tension side is abnormal, the controller would send out signals to trip out the circuit breaker. When the three-phase voltage at the low tension side is lower than 50% of the normal voltage, the controller would not send out operation signals so as to avoid tripping of all low-voltage switch gears due to 10kV high-tension line tripping or power-off service. In addition, integrated power distribution test instrument with remote metering and telecommunication functions can be added as required.
High-voltage metering
The electrically-controlled prefabricated substation is a new product designed on the basis of YBM- 12/0.4 prefabricated substation. Besides keeping the original features and functions, it also has electrically operated mechanism with load switch and dedicated controller to realize automatic switchover between duplicate supplies, and it can also realize remote control, remote signaling and remote tuning of prefabricated substations via RS485 interface.
The electrically-controlled could substation can realize the following
functions:
Electrical operation of local load switches;
Electrical operation of remote load switches;
Automatic switchover between duplicate supplies (reserve supply can be enabled within 20 seconds);
Single-tool four position switch with natural locking function is adopted to ensure reliable power supply switchover and prevent closed-loop operation of duplicate supplies;
Remote communication.
Landscape prefabricated substation
Landscape-type prefabricated substation is a new-style product developed on the basis of YBM - 12/0.4 prefabricated substation of our company. The main body adopts cold-rolled plate or corrosion resistant plate with wood lining to present elegant appearance. The product is mainly applied to parks and residential areas to form landscape in cities.
1. The major structure adopts cold-rolled plate or corrosion resistant plate and the external wood plate for decoration adopts fir, pine wood, etc. That go through corrosion protection and fireproof treatment;
2. The top adopts color steel plate structure to match the lines of wood plate and achieve more elegant and natural appearance;
3. The smart ventilation design on the top results in good ventilation effect;
4. Rust prevention, heat insulation and condensation removal are realized
